The Blue Room in Curaçao is a small, air-filled sea cave near Mushroom Forest in the Santa Cruz Plantation area of Banda Abou, where sunlight entering through an underwater opening turns the water inside an electric, glowing blue.
Sitting in only about 5 meters (15 feet) of water, it’s one of the rare Curaçao experiences that belongs equally to divers, snorkelers, and underwater photographers. What began as a quiet spot for divers to off-gas between dives at nearby Mushroom Forest has become one of the most talked-about sea caves in the entire Caribbean.
This guide covers everything you need to know about diving and snorkeling The Blue Room — its story, its marine life, when to go, and how to build it into a personalized Curaçao dive vacation.

What is The Blue Room in Curaçao?
The Blue Room is a shallow sea cave carved into the cliffside at the end of a roughly one-kilometer stretch of coastline in the Santa Cruz Plantation area of Banda Abou, right next to the celebrated Mushroom Forest dive site. From the surface, the entrance is easy to miss — a narrow opening at water level that most divers swam right past for years on their way to the reef.
Duck beneath that opening, though, and the cave reveals an air-filled chamber with a resident colony of small bats overhead. Sunlight filtering through the underwater entrance refracts through the crystalline water, filling the chamber with a saturated, electric blue that has made this sea cave one of the most photographed dive and snorkel sites in Curaçao.
Location and How to Get There
The Blue Room sits within the Santa Cruz Plantation, near the village of Barber on Curaçao’s rugged northwest coast. Most visitors reach it by boat with a local dive operator, though experienced hikers can also approach on foot from Playa Santa Cruz. Because the site sits along an active boat diving route on the west coast, a guided boat trip is the easiest and safest way to visit.
Depth, Conditions and Difficulty
The Blue Room is beginner friendly. The chamber sits in approximately 5 meters (15 feet) of water, and the swim-through itself is short and calm on typical days. It’s rated suitable for beginner divers and confident snorkelers alike, though conditions along this stretch of coast can shift with swell, which is why a knowledgeable local guide matters.

The Story Behind The Blue Room
From Off-Gassing Stop to Caribbean Icon
The Blue Room didn’t start out as a destination at all. For years, divers surfacing from dives at Mushroom Forest used the little cave as a convenient spot to off-gas between tanks, ducking in for a few quiet minutes before heading back to shore or the boat. Snorkelers exploring the shoreline discovered it just as easily — the entrance requires nothing more than a single breath and a short duck under the rock.
Amos Nachoum and the Discovery of the Light
The Blue Room’s transformation from local secret to Caribbean icon traces back to 2006, when acclaimed wildlife photographer Amos Nachoum visited Curaçao on a photo expedition with then–Sport Diver editor Ty Sawyer. Nachoum, a lifelong “light wrangler,” described the quality of light inside the cave as “perfect.” Word spread through the underwater photography community, and what had been a novelty on Curaçao’s west end quickly became a must-visit site for photographers, divers, and snorkelers from around the world.
Diving The Blue Room
What Divers Will See
Beyond the light itself, The Blue Room rewards a slower look. The cave walls are covered in orange cup coral, which opens most visibly at night but adds vivid color to photos even by day. Copper sweepers — small, gold-bronze fish known for swimming upside down — shelter in the cave’s shadows year-round, drifting in loose schools near the ceiling.
Best Time to Dive — Silversides Season
Late August through September is the signal time to dive The Blue Room. During these weeks, dense schools of silversides move into the cavern, flashing through the shafts of light like liquid mercury. It’s a dramatically different experience from the rest of the year and one that underwater photographers plan trips around.
Snorkeling The Blue Room
Why It’s One of Curaçao’s Top Snorkeling Sites
You don’t need a tank to experience The Blue Room. Its shallow depth and calm, air-filled chamber make it one of the most accessible and rewarding snorkeling sites in Curaçao, and it’s often the highlight of a west-coast snorkel outing alongside Mushroom Forest and Black Sand Beach. Confident swimmers can duck through the entrance on a single breath; less experienced snorkelers are best paired with a guide who can talk them through the short swim-through.
Ocean Encounters Trips from TUI BLUE Curaçao
The Blue Room is also reachable from the island’s east side. Ocean Encounters runs Blue Room snorkeling trips departing from the all-new TUI BLUE Curaçao, located at Santa Martha Bay near the village of Soto. It’s a convenient option for guests staying at this newly developed, sustainability-focused resort who want to add The Blue Room to their west-coast itinerary without arranging separate transport.
GO WEST Diving Snorkel Trips from Playa Kalki
GO WEST Diving, based at Playa Kalki in Westpunt, runs guided west-coast snorkel and boat trips that regularly include this site alongside Black Sand Beach and the wreck of the Catherine. Their local team knows the entrance, the current conditions, and the safest way in — valuable reassurance for anyone snorkeling the cave for the first time.
Tips for a Memorable Visit
Best Time of Day for the Light
The vivid blue glow depends on the angle of the sun striking the underwater opening. Mid-morning through early afternoon, when the sun sits higher overhead, produces the most vibrant light inside the chamber. An early-morning or late-afternoon visit will still be memorable, just less electric.
Safety and Responsible Diving
- Dive responsibly and always follow your guide’s briefing.
- Review Curaçao’s shore diving safety guidelines before any independent entry.
- Because of recreational and commercial boat traffic along this stretch of coast, an inflated surface marker buoy is required for anyone entering from shore.
- Review the top eco-diving tips for Curaçao so your visit supports the reef rather than stressing it.
What to Bring
A waterproof camera or underwater housing is worth packing — the interplay of light and water inside the cave is one of the most photogenic scenes in Curaçao. A dive light is useful for divers who want to bring out the orange cup coral’s true color, and reef-safe sunscreen protects the surrounding marine environment.
